[Bug 2078602] [NEW] one-liner from upstream fixes plocate free() crash

[Scott Mcdermott]

Public bug reported:

My `plocate 1.1.15-1ubuntu2` on ubuntu22 amd64 with all patches applied is now crashing with:
```
free(): invalid pointer
Aborted
```
on any `locate` (which is `/usr/bin/plocate` via `alternatives`).  After getting the source and applying sole upstream patch 7f39444 on top of 1.1.15 (see attached) it fixes the issue and locate succeeds (no need to regen db).  This patch changes a single `free()` call in IOUringEngine() to a `io_uring_free_probe()`.

Please apply to ubuntu22 or bump upstream base to minimum 1.1.19 which
is the first tag to contain 7f39444.  Thanks.
